Documentation

Learn how Airlingo works, how to start reading with the Chrome extension, and what changed across releases.

Start here

Airlingo is built for serious second-language readers who want translation to support reading without replacing the original page. The docs focus on the extension workflow, Deep Read behavior, feature usage, and product updates.

Use the guide when you want to install Airlingo, understand credits, or learn how each reading feature behaves. Use the changelog when you want to see what changed in recent product updates.

Docs map

• Guide: onboarding, extension installation, Deep Read, read modes, credits, and everyday reading flow.
• Changelog: release notes for the web app, extension, billing, and demo experience.

Product principle

Airlingo keeps the source page primary. Help appears at the exact moment a word, sentence, or context needs clarity, then gets out of the way so you keep reading in the language you are learning.
